Dawn of the Grey Tower

North of Dragon's Crest Mountain, the frozen wasteland. Anyone who has really been to the northern wilderness will inevitably notice a strange fact, that is, although it is snowing here all year round, the snow on the ground is unexpectedly thin.

Of course, the thinness here is a relative concept. The snow covering here can still easily reach the middle of the calf, but compared with the ultra-thick snow that can bury people in half or even cover the top, it is unbelievably thin. .

This kind of situation is almost all over the whole wasteland, whether it is under the gray tower or at the foot of Longji mountain, there are few undulating landforms on the flat wasteland, and some are only white snow with a uniform thickness.

The gray robes are more or less curious about the cause of this phenomenon, but they are not their own teachers after all, and they don't have such a grand pattern to easily find the cause of some abnormal weather.

In fact, in this era when satellites or other macro observation methods do not exist, no matter how knowledgeable people are, they can only judge the weather from the immediate situation. It is not that they do not have the ability to understand macro weather changes, but It's the lack of that vision.

Therefore, it is no wonder that the cheese and the cursed crow numbly accepted the state of the ice field. Sometimes the more accustomed to the environment, the less people can perceive its special features.

This has nothing to do with knowledge, it is purely a mutual constructive relationship between thinking and the environment. How exactly does the living environment appear in the mind.

The gray robes each have their own environment they want to live in, so they seldom come back after leaving the gray tower. But they also have their own ways of dealing with the wilderness that raised them. The sled is recognized by the gray robes as one of the best means of transportation in this land.

There are few direct contests between the gray robes, except for the sled. In fact, the gray robes have held more than one sled competition. The venue is the ice field under the gray tower. Only here can anyone use it, and everyone can use it. In terms of transportation, they will rarely give up disputes and recognize that each other has value that can compete with each other and learn from each other.

For these reasons, Cheese and Curse Crow naturally wanted to make a sled after leaving Longji Mountain, but there was still a problem before they started. That is, most of the sleds need to be pulled by creatures, and now unless the two gray robes take turns playing the role of pack animals, they have no way to provide stable power for the sleds.

And the two who had obviously used stupid methods to climb the mountain had no patience and stamina to keep their feet on the ground. For the next possible battle, they desperately needed a fast and convenient sled.

"I think the wind is fine. With the help of the wind like a sail, we don't need pulling force, and we can slide all the way." Curse Crow quickly gave his suggestion. Sailing on dry land is a joke, but sailing on snow is not. Certainly, the design of the sled and sail is indeed worth trying.

"And then being thrown out when turning, or being carried by the wind where you don't want to go at all? The boat is stable in the water because a considerable part of its bottom is sunk in the water, and the sled is floating on the snow. That would make it extremely unstable. It would make driving unnaturally, unsafely."

The design of the windsurfing sled was of course proposed by Gray Robe, and there were even many prototypes manufactured based on this idea, many of which were equipped with a keel-like structure that could penetrate under the snow to ensure the stability of the sled.

But the problem is that the ice field is not really flat. Like a big ship running aground in shallow water, the keel of the sailing sled can easily scratch the protruding part under the snow, which will bring about violent bumps on the entire ship, and even the terrible result of rolling out.

Therefore, for high-speed sleds, sail design is tantamount to a gamble on the road conditions.

"Well, I remember that some people's sail prototypes fell very ugly. So what do you suggest?" Curse Crow folded his arms, and he was not annoyed because Cheese rejected his design. It's just that I'm confused about what other powers I can use besides wind power.

Cheese tidied up his clothes seriously, and then took out the alchemy dice, "We can make a large number of magnets and use magnetism as power. This way we won't be afraid that the wind speed will be too fast to be uncontrollable."

Magnet has the function of a pointer, and there will be attraction and repulsion between each other. This is not a knowledge that few people know among mages. Many people have made conjectures and inferences about the origin of magnetism and what the compass is pointing to, but there is no definite conclusion due to the limitations of astronomy.

But this does not prevent people from learning to use the discovered laws to manufacture various products that work due to magnetism, such as the early compass. Gray-robed mages have bolder ideas than ordinary craftsmen, and technologies that the secular society does not have, so their application of magnetism can be more than just identifying directions.

All kinds of organs using magnetism, and even using magnetism to control iron powder to form a magic circle, are all means available to spellcasters. With alchemy dice, it is not difficult to manufacture a large number of magnets. It should be feasible to use these magnets as power to build sleds.

"Have you ever calculated the ratio between the weight of the magnet and the pulling force it provides? You have to understand that if the magnet is really that good, then when you make a magnet, it shouldn't stay in your hand, but Fly straight out to the north or south."

Curse Crow mercilessly pointed out the biggest problem in the cheese magnetic sled concept. If the kinetic energy of the wind sled is too fierce, then the magnetic force is seriously insufficient.

To achieve magnetic propulsion, they still need to overcome many problems related to magnets and magnetic fields, and now is obviously not the time.

Cheese spread his hands, saying that there is no problem with what the same door said. He also thought that maybe he could learn from the sun core of the City of Ten Thousand and use the sunlight in the breath of dawn as an energy source.

The way to convert sunlight into usable energy can never be simple~www.wuxiaspot.com~ Just like the effective use of magnetism, it cannot be effective in the short term.

"Then why don't you just curse the sledge? I remember that there should be some feasible spells in the curse, right?"

Stories often have cursed scarecrows wandering around, or cursed furniture that moves by itself, and curses can indeed make things that don't have the ability to move forward like living things. Curse the sleigh? Sounds very mage-like.

"The spell you mentioned can't control the direction. The curse can give the non-living body a single command at most. How it understands this command and how it responds to it is almost completely random. If I curse the sled, guess what? Will it suddenly stand up and start running, throwing us halfway?"

Curse Crow is a true master of conjuration, and if he says curses don't work, that's the truth. In fact, thinking about it, if a curse could make the sled move on its own, he wouldn't have come up with the idea of ​​sailing at all.

"In this case, should we change our thinking? The sled is still a normal sled. But maybe the thing that pulls the sled can move?"
